Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473838, here are decompositions:

29 + 31473809 = 31473838
59 + 31473779 = 31473838
131 + 31473707 = 31473838
239 + 31473599 = 31473838
257 + 31473581 = 31473838
359 + 31473479 = 31473838
401 + 31473437 = 31473838
479 + 31473359 = 31473838

Showing the first eight; more decompositions exist.
